A domain name, or peer node IP address be non-trusted node set in an IP address when, determine peer node
For non-trusted node.
Step 303：When packet includes request message, response message corresponding to packet is determined, request message is used for
Acquisition request feedback data；Feedback data in response message corresponding to packet is replaced with into the first preset data, replaced
Response message after changing；Response message after replacement is sent to peer node.
Exemplary, when fire wall can not stop when data request information is transmitted to terminal of non-trusted node, terminal
When receiving the request message that non-trusted node is sent, can be determined according to normal request responding process comprising feedback data
Response message, using the response message comprising feedback data as the first response message；Response message is being sent to non-trusted node
Before, the feedback data in the first response message is replaced with into the first preset data, obtains the second response message, terminal finally will
Second response message is sent to peer node.
Exemplary, the first preset data is：Encryption data, mess code data, full 0 data or complete 1 data, encryption data
For：The data obtained after feedback data is encrypted using default AES.It is understood that the first response message
In the feedback data that includes be valid data, the first preset data included in the second response message obtained after replacement is
Invalid data.Non-trusted node will be considered that when receiving the second response message of terminal transmission has normally stolen number of terminals
According to the request of data to the terminal will be stopped.
Exemplary, default AES can be：IDEA(International Data Encryption
Algorithm, Chinese IDEA), DES (Data Encryption Standard, Chinese data
Encryption standard), MD5 (Message-Digest Algorithm 5, Chinese Message-Digest Algorithm 5) etc..
It should be noted that when non-trusted node detects to the response message received, because encryption data does not have
There is any detection foundation, therefore be easier to believe non-trusted server successfully to steal terminal data, and stop to the end
The request of data at end.
In the embodiment of the present invention, the response message after replacement is used to indicate that peer node stops continuing to send packet.
Step 304：When packet does not include request message, packet discard, or by the data division in packet
The second preset data is replaced with, the packet after replacement is stored；Generate response；Response is sent to opposite end
Node, response are used to indicate that packet normally receives.
In the embodiment of the present invention, packet does not refer to that the packet issues for non-trusted node to terminal including request message
Data, rather than data for acquisition request terminal.Packet includes：Head and data division, wherein, data division can
Can take viruliferous threat data, terminal receives and may threaten terminal security after data storage bag.
Exemplary, when fire wall can not stop the packet issued of non-trusted node, terminal is receiving non-letter
During the packet for appointing node to send, directly by data packet discarding；Or the data division in packet is replaced with second and preset
Data, the packet after replacement is stored.Exemplary, the second preset data is：Mess code data, full 0 data or complete 1 number
According to.
Generate response；Response is sent to peer node；The response is used to indicate the packet just
Often receive.
In the embodiment of the present invention, response is sent to peer node, to inform data that peer node this time issues
Bag has been received normally, and avoids peer node from persistently issuing packet.
When actually implementing, the packet after storage is replaced can also include afterwards：It will be replaced after default time interval
Packet after changing is deleted.When actually implementing, if terminal directly can be by non-trusted node by the operation of data packet discarding
Detect, and carry out packet and resend；In order to avoid such case occurs, first the data content in packet can be replaced
